The invention discloses a braking control method for a forward forklift with biased driving wheels, which comprises the following steps of: detecting a voltage signal of a forklift braking switch, judging whether a driver has a braking intention or not according to the voltage signal, and if so, monitoring a forward switch and a backward switch of the forklift; according to the collected forward switching value signal and the collected backward switching value signal, it is judged that the forklift travels along the driving wheel side or the bearing wheel side; the rotating speed of a forklift traction motor is obtained in real time, and the left offset torque M of the inertia force and the driving wheel friction force on the left bearing wheel in the forklift braking state is obtained through calculation; according to the left offset torque M and the driving state, whether the driving wheel is in a sideslip state or not is judged, and if yes, the braking torque of a traction motor is reduced so that the driving wheel can not slip. According to the invention, the braking accuracy and convenience of the forklift can be improved, and the operation safety of the forklift is improved.
本发明公开了一种驱动轮偏置前移式叉车的制动控制方法,包括:通过检测叉车制动开关的电压信号,并根据所述电压信号判断驾驶员是否有制动意图,如果有,则监测叉车的前进开关和后退开关;根据采集到的前进开关量信号和后退开关量信号,判断出叉车行驶沿驱动轮侧行驶或承载轮侧行驶;实时获取叉车牵引电机的转速,并计算得到叉车制动状态下惯性力及驱动轮摩擦力对左承载轮的左偏置力矩M;根据所述左偏置力矩M及行驶状态,判断驱动轮是否处于侧滑状态,如果是,则降低牵引电机制动力矩,以使驱动轮不打滑。本发明能提高叉车制动的精准性和便捷性,增加叉车运行的安全性。
